I have an HQ with a 304 engine, Holley carburetor and electric fuel pump. In general, should electric fuel pumps have a pressure regulator between it and the carburetor ? I don't have a separate regulator, and I don't think the pump has a built in one. I've always wondered is I should have one. The fuel pump I have is this one: https://fuelflow2020.nz/?page_id=167
Carburetor is 4165 type (List =6498) Tks&Rgds.

Have a look on Holley’s site, they should have the recommended fuel pressures for their different carbs. If you can’t find it I’ll see if I can later. |

Have a watch and read. Might help: https://www.holley.com/b...or_carbureted_vehicles/
This Holley pdf suggests 5-7psi, with minimum of 4psi at engine redline and 7psi at idle. Very different specs to your fuel pump! https://documents.holley.com/199r7923-2rev2.pdf
I think that pdf is applicable to your Holley, I read a 6498 as a 650cfm spreadbore double pumper. |
